' HOSE-COUPLING.

Specification of Letters Patent.

Patented May 2, 1911.

Application filed September 27, 1910. Serial No. 584,079.

connect together two sections of any hose.

An object of the invention is to provide'a device which will be simple in construction, inexpensive to manufacture, strong, durable, and attachable and detachable in the shortest possible space of time.

A further object of this invention is to provide a hose coupling comprising a pair of interfitting members having an eflicient automatic packing disposed therebetween.

These and'further objects together with the construction and combination of parts will be more particularly described hereinafter and set forth in the appended claims.

Reference may be had to the accompanying drawings in which like reference characters denote corresponding parts in the several views, and in which Figure 1 is a' side view and elevation partly in section showing the underlying construction; Fig. 2 is an end view looking from right to left in Fig. 1 Fig. 3 is a front view of the packing ring; Fig. 4 is a vertical section through the packing ring; and Fig. 5 is a perspective view of the spiral spring.

Referring more articularly to the separate parts of the d evice, 1 indicates a hose section which is to be attached to a similar hose section indicated at 2. Secured to the hose section 1 in any suitable manner, as by being provided with a corrugated interior indicated at 3, there is provided a coupling member 4 which is formed at its engaging end withan enlargement 5 which is preferably conical in shape, and having a taper conver ing toward the open end of the member. ecured in a similar manner to the hose section 2, there is provided a cooperating coupling member 6, which has a tapered conical socket to fit the conical extremity of the coupling member 4. In order that there may be a perfectly fluid tight joint be tween the couplin members 4 and 6, one of them, preferably t e member 6, is provided with a circular recess 7 in which is located a packing ring 8, having a tapered inwardly extending flange 9, which is adapted to engage the conical surface of the coupling member 4. Also within this recess 7 there is provided a spiral spring 10 which is adapted to urge the flange 9 into tight and yet yielding engagement with the coupling member 4 so as to prevent the leakage of fluid and yet permit the relative adjustment of the members 4 and 6.

In order to lock the coupling members 4 and 6 together, the member 6 is also enlarged to form a cylindrical projection or lug similar to that formed by the enlargement 5 which is engaged by the inwardly curved ends 11 and 12 of spring clamps 13. Any

suitable number of these spring clamps may be provided, and they may be secured to one of the coupling members in any suitable manner, as by means of a spring clip 14, which in this case is'shown as engaging the coupling member 6. The manner of securing the spring clamps 13 to the spring clip 14, which in this case is shown in the form of a broken ring having its ends tapered to permit a more ready attachment thereof, may be of any suitable character such as by means of rivets 15. It will thus be seen that it is simply necessary to force the coupling member 6 on to the coupling member 4,'when the curved ends 11 of the sprin clamps 13 will automatically snap over t e enlargement 5, thereby securing the coupling members together. Inasmuch as the spring 10 forces the ring 8 in engagement with the coupling member 6, and the flange 9 thereof in engagement with the coupling member 4,

a perfectly fluid tight joint will be made.

While I have shown one embodiment of my invention I do not wish to be limited to the specific details thereof, but desire to be protected invarious changes and alterations which may come within the scope of the appended claims.

Having thus described my invention,- I claim as new and desire to secure by Letters Patent r 1. The combination with a pair of coupling members having coiiperatlng conical surfaces, of means for securing said coupling members together, anda packin ring adapted to form a fluid tight joint etween said coupling members, comprising a body ortion and a flange, and a spring adapte to urge said body portion into engagement with ,one of said coupling. members and said flange into engagement with both o f-saidcoupling members.

. 2. The combination with a pair of conpling members having conical cooperatin surfaces, of acking interposed between sai surfaces, ans means for secliring said coupling members together, comprising a plurality of spring clamps each bent at one end and intermediate its ends to form engaging portions adapted to engage enlargements on said coupling members, and a sprin clip for engagin one of said coupling mem rs and removab y securing said spring clamps to one of said coupling members.

3. The combination with a con ling member having a conical socket therein and also having an annular cavity racing on said socket, of a acking ring in said cavi having a radially-extending flange promoting inwardly be 0nd the conical surface of sai socket, anot er coupling member having a conical ta er adapted to be inserted in said socket and through the opening inclosed by said flan e and in contact with said flange, a

spring a apted to hold said flange in tight rel tionwith both of said coupling members, and means for securing said coupling membcrs together.

In testimony whereof I- have signed my name to this specification in the presence of two subscribin witnesses.
